STMicroelectronics, standard: AEC-Q100 Ovladač IO napájený baterií 48 V 48V 5.4V 200 mA, počet kolíků: 64 kolíkový, TQFP

The STMicroelectronics L9963E is a Li-ion battery monitoring and protecting chip for high-reliability automotive applications and energy storage systems. Up to 14 stacked battery cells can be monitored to meet the requirements of 48 V and higher voltage systems. Each cell voltage is measured with high accuracy, as well as the current for the on-chip coulomb counting. The device can monitor up to 7 NTCs. The information is transmitted through SPI communication or isolated interface.

• AEC-Q100 qualified
• Measures 4 to 14 cells in series, with 0 μs desynchronization delay between samples. Supports also Busbar connection without altering cell results
• Coulomb counter supporting pack overcurrent detection in both ignition on and off states. Fully synchronized current and voltage samples
